First and only 3D-graphical Vector Accelerometer in App Store: Smoothly visualize and measure the current acceleration. It can be used on earth, on moon or in orbit (where relative would be equal to absolute mode - please prove) to visualize the direction and strength of the gravitation - or simply at home to measure the g-forces you reach while shaking your phone - however be warned if you tend to get to the limits! :-). A fun application is to place the iPhone/iPod steady in your car (or any other moving vehicle), go to relative mode, zero it once when you are standing and then see the current g-forces in effect while you drive (e.g. what g-force does your car get when you accelerate?). The application has five different display modes for acceleration visualization: - Absolute Mode: Displays the reverse acceleration of the iPhone (1g up when hold steady). - X-Rotation - Y-Rotation - Z-Rotation: The arrow will display the rotation around the X-, Y- and Z-Axis of the iPhone. The digital indicator shows the angle numerically (-180° - +180°). A way to calibrate will be added with one of the next updates, so you could use this as a level. - Relative Mode: This mode shows the relative strength (absolute minus compensation vector) of the acceleration. For a detailed documentation, please visit our product homepage. For recreational use only. However it CAN (!) be very accurate. The measurement is performed as good as possible (we try our best) by using the inbuilt accelerometer and magnetometer to their limits. The range of the accelerometer typically has a max of ±3g (~4.2g displayed here if combined). However, tell us your experience! Check out all our products (free and paid) on www.plaincode.com

Verdict

The call

The clearest difference is rating: Physics Toolbox Sensor Suite at 4.7 against AccelMeter's 2.7. Physics Toolbox Sensor Suite also leads on review sentiment (80% vs 48%) and update cadence (weekly vs every 6 months). AccelMeter's advantage is in-app purchases (none vs 1) and iOS requirement (10.0 vs 16.0). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Physics Toolbox Sensor Suite holds the better App Store score, 4.7 against 2.7. That said, the two scores are not equally well evidenced: Physics Toolbox Sensor Suite has 1.8K ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 48% of AccelMeter's written reviews are positive against 80% of Physics Toolbox Sensor Suite's.

UpkeepUpdate frequency

AccelMeter ships an update every 6 months, Physics Toolbox Sensor Suite weekly. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
